android write sqlite file with arabic text

Question

I have a custom method to
copy the database from assets folder to the database directory

    AssetManager am = myContext.getAssets();
    OutputStream os = new FileOutputStream(DBFile);
    DBFile.createNewFile();
    byte []b = new byte[1024];
    int i, r;
    String []Files = am.list("");
    Arrays.sort(Files);
    for(i=1;i<5;i++)        {
        String fn = String.format("0%d.database", i);
        if(Arrays.binarySearch(Files, fn) < 0)
            break;
        InputStream is = am.open(fn);
        while((r = is.read(b)) != -1)
            os.write(b, 0, r);
        is.close();
    }
    os.close();

All works as expected and the database is copied to the apps database directory except for when I change the android system language (settings>language) and set the system language as arabic, and re install the app, it crashes and the database file isn't copied to the databases directory. It's just a blank file.

Im thinking maybe i should read the database file with an encoding specified because something must change in java dhe moment I change the language.
